Optical projection tomography (OPT) is a tomographic 3D imaging technique used for specimens in the millimetre scale.

The role of material production as a driver of environmental impacts is increasing, which calls for a better understanding of global material flows. This thesis explores the role of in-use stocks of products, buildings and infrastructure as a key driver of global material demand and discusses the implications…

Decarbonizing the building stock is critical for realizing the climate-neutral target for the Netherlands.

Hoe moet de EU omgaan met Oekraïne, Wit-Rusland en Moldavië? Hoe kunnen we de Europese Unie helpen om, in een uiterst moeilijke en veeleisende geopolitieke context, zijn politiek ten aanzien van deze landen te heroverwegen?

n this PhD thesis, the recombination of different atomic lattices in stacked 2D materials such as twisted bilayer graphene is studied. Using the different possibilities of Low-Energy Electron Microscopy (LEEM), the domain forming between the two atomic layers with small differences is studied.

Streptomyces present a valuable platform for natural product discovery. Lugdunomycin is a novel angucycline-derived polyketide from Streptomyces sp QL37, with unprecedented skeleton and antimicrobial activity.

Streptomyces bacteria are a valuable source of natural products, many of which are used in the clinic or in biotechnology.

The global agri-food system plays a critical role in food security and environmental issues.

Afhankelijk van de omstandigheden kunnen korrelige materialen zoals zand verschillende vormen aannemen. Hoe komt deze verandering en het uiteenvallen van deze materialen tot stand? Natuurkundige Corentin Coulais ontwierp een model om de geheimen achter dit fenomeen te ontrafelen. Op 7 november verscheen…

Zoeken naar materialen met eigenschappen die in de natuur niet voorkomen. Daar gaat de oratie van hoogleraar Sense Jan van der Molen over. Hij vertelt in het Leidsch Dagblad en op BNR Nieuwsradio over hoe hij ‘sjoelt met elektronen’ om zulke materialen te bestuderen.

Materials balances have been used in the recent past for the analysis of substance oriented environmental problems and the formulation of measures for environmental policy. In this study an integrated tool, based on the materials balance principle, has been developed for the analysis of both environmental…

Natuurkundigen van de Universiteit Leiden en Stichting FOM hebben een manier gevonden om de eigenschappen van 'slimme', door de mens ontworpen materialen beter te begrijpen. Hun methode onthult hoe op elkaar gestapelde laagjes in zo’n materiaal samenwerken om het geheel tot een hoger niveau te tillen.…
